Not sure this fits the template exactly -

Robert De Niro ? He has seven children: 7 kids with four different women and the youngest is just one year old.

Al Pacino
Became a father at age 83 in 2023


Jeff Goldblum
Became a father at age 62 in 2015, and had another son in 2017 to his third younger wife.

Mick Jagger
Has fathered children well into old age. 8 children with five different women.

Warren Beatty
Has fathered children well into old age - linked to over 100 female celebrities before marrying much younger Annette Benning and having 4 kids in his 60s

Rupert Murdoch
Has fathered children well into old age - married 5 times and six kids.

I just rewatched “It’s Complicated” starring Alec Baldwin and Meryl Streep. He plays a midlife crisis man who divorces his wife to marry his much younger AP. He soon regrets this decision because he now has to go through fertility treatments to have a babies with his young wife. He and his ex laugh about how old he will be attending a graduation, as he realizes the huge mistake he made.
I wonder if he thinks of the irony now having so many children with Hilary in his 60s. lol

Can you think of other examples?
